EEPECIPICATION forming part of Letters Patent No. 296,670, dated April 8, 188%.

- Application filed November 15, 1883.

To osZZ whomit may concern.-

Be it known that 1, WILLIAM G. BRYAN, of Nashville, in the county of Davidson and State of Tennessee, have invcntedcertain new and useful Improvements in Dumping-Wagons; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to theaccompanying drawings, forming part of this specification, and to the figures and letters of reference marked thereon.

My invention relates particularly to that class of wagons used for transporting bricks, coal, and similar material, though of course it is generally applicable to wagons used for other purposes. Its novelty consists in a certain improved construction and combinations of parts, hereinafter to be described and claimed, whereby the wagon is rendered self-dumping.

My invention will best be understood when described in connection withthe accompany ing drawings illustrating it, wherein- Figure 1 represents a top plan view of my improved wagon; Fig. 2, a side elevation of the same; Fig. 3, a longitudinal vertical section taken on the line :27 x of Fig. 1.

Similar letters of reference in the several figures denote the same parts.

The letter A represents the rear axle of the wagon, and the letter B the front axle of the same, both axles being provided with ordinary transporting-wheels, as shown. The frontaxle has mounted upon it and connected to it through an ordinary fifth-wheel a bolster, C, and supported upon this bolster and upon the rear axle is an inclined frame, D, composed of side bars and a front bar or cross-piece, as shown.

E represents the body of the wagon, supported upon the side bars of the frame D by a cross-bar, F, at the rear, rollers G at the middle, or thereabout, and smaller rollers 72. h at the front end. The side bars of the frame are protected upon their upper bearing-surfaces by metal protecting plates or tracks I, extendl ing from a point forward of the bearing-points of the front rollers, h, back of the rear axle, where they are curved up and formed into guards or stops J. ,The portions of the side bars of the frame which extend past the stops or guards J and upon which the cross-bar F of the body rests, are also protected or shod (No model.)

with metal plates K. Secured to the body at or near the point of attachment of the rollers H are downwardly-projecting arms L, which serve to hold the forward end of the body in place and prevent it from moving laterally. The rollers or wheels h are preferably provided with flanges, so as to prevent lateral displacement of the body at the middle, and also for the purpose of guiding and properly directing the body when moving down the in clin ed plane, the downwardly-proj ectin g arms also assisting in the accomplishment of this end.

To the forward portion of the body, at opposite sides tl1ereof,'are pivoted, so as to swing up and down freely, hooked arms M M. WVhen the body is moved up the inclined frame from the rear, these arms M hang down, with their forward shouldered ends below or on a line with the bottom of the body, and as the body advances up the incline they strike inclined guides N N, secured to the bolster, and are raised by said guides and caused to pass up over and engage with a cross bar or rod, 0, extending from side to side of the frame D. Mounted upon a rock-shaft, P, extending from side to side of the front end of the frame D, are two U-shaped arms, Q Q. The general form of these arms is U-shaped, thoughthe upper part or branch is slightly longer than the lower part or branch. Normally these U-shaped arms stand opposite the inclined guides N N, with their upper branches above the cross-rod E and their lower branches below said cross-rod, as shown in Fig. 3, they being held in this position by the tension of acoiled spring, R, secured to the rock-shaft P, and having its free end bearing against cross-rod 0. As the shouldered ends of the hooked R, and serve to hold the said hooked arms M in engagement.

If it is desired to dump the load, the rockshaft P is rocked by means of ahand-lever, S, applied to one of its ends, and the U-shaped arms Q Q are caused to swing up, and in so doing positively lift the ends of the hooked IOO arms M M and free them from the rod 0. The body, being thus released, moves down the incline frame upon the rollers G and h until the cross-bar F of the body at the rear passes off of the side bars, whereupon the body tilts down upon the aXles of the wheels or rollers G as a center and strikes two other rollers, T T, located on the frame over the rear axle, as shown in Fig. 3. The body, in its tilted condition, continues down the inclined frame until its rollers G come in' contact with the stops or guards J. After the load has slid out of the body, the latter is tilted up until its forward rollers, H, again rest upon the incline fra1ne,and it is then moved up the frame until its hooked arms again engage with the crossrod I, as before. It will be observed that as soon as the hooked arms are disengaged from the rodPby the tilting of the rock shaft the dumping of the load is effected automatically.

here an autoinatically-opening end-gate is not employed, it will be necessary to let down the end-gate before operating the lever S to disengage the hooked arms.

Having thus described my invention, 1 claim as new- 1. In a dumping-wagon, the combination, with the inclined frame, of the body provided permit the body to be tilted upon the axles of said rollers, substantially as described.

2. The combination of the inclined frame with the body, the hooked arms pivoted to the body, the incline for automatically raising the hooked arms, and the rod with which the hooked arms engage, substantially as de scribed.

3. The combination, with theinclined frame, of the body, the pivoted hooked arms, the rod with which they engage, and the U-shaped arms mounted on the rock-shaft, substantially as described.

4. The combination, with the inclined frame, of the body, the pivoted hooked arms, the inclined guides for raising said arms, the rod with which the arms engage, the rock-shaft and its U-shaped arms, and the spring upon the rock-shaft, substantially as described.
